The sea otter also eats fish, but its favorite foods are marine invertebrates like sea urchins, molluscs and crabs.

Unlike otters, the beaver is a "vegetarian," as its food comes mainly from trees and grasses. It also likes the barks, buds, and roots of water plants.

Difference in shape

The beaver is famous for its distinctive tail that is wide, flat and paddle-shaped.

The sea otter is known for its unusual "backstroke." Sea otters usually hold hands with each other to prevent the current from separating them. Besides, the sea otter typically rubs its face with its paws, since the fur on the face helps to keep its paws warm.
